The JN516x Data Sheet, Chapter 14 says:
JTAG Test Interface
The JN516x includes an IEEE1149.1 compliant JTAG port for the purpose of manufacturing test. The software debugger is not supported with this product.
Does this mean that I can't use the BeyondStudio IDE to do JTAG Debugging (breakpoints, etc...) on the JN5168 Module? If JTAG debugging IS supported, then what is the meaning of this statement?
If JTAG debugging is supported, I'd like to make a provision on my target PCB to connect the Beyond Debug Key directly to my target PCB. I have reviewed the information in the Beyond Debug Key document, but is there an NXP App Note specifically showing how to accomplish the JTAG interface to the JN5168 (e.g. Pull-Up resistors, specific connections, any necessary adjustments in the build (or otherwise) to use JTAG Debugging?
Surely this must be a common question, but I don't seem to be able to find any single definitive document with instructions about how to do this.
Thanks in advance for answering the above questions and for pointing me to the appropriate document(s).

Please note, I AM aware of JN-AN-1203, but this document is only useful if someone has purchased the Evaluation Kit (NXP JN516x-EK001) and the JTAG Expansion Board (NXP DR1222), as all the instructions in this App Note describe how to configure and plug the various boards together, but provide NO schematics for understanding what the actual connections are between the Beyond Debug Key and the JN5168!
My goal is a simple one. How to interface the Beyond Debug Key directly to a JN5168-001-M0x module. Particularly Pins 17 & 19 of the Beyond Debug Key. It appears that possibly Pin 17 is used in conjunction with the Reset line to signal the JN5168 to initiate JTAG by pulling the SPIMISO line low at reset?
Also pins 17 & 19 on the Beyond Debug Key are supposed to be for a UART debug port, but on the JN5168 Module RXD0 and JTAG_TDI share the same pin...
A simple wiring diagram showing how to connect the Beyond Debug Key to the signal lines of the JN5168 is all I'm looking for, but I can't seem to find this anywhere!
Can anyone please provide this simple connection interface description?
Thank You!
